BDS-18964Cannot call functions in a beforeEvent
Mojang please fix this, it is limiting us developers and causing immeasurable headaches. I'm tired of having to come up with dumb workarounds that bloats my code, wrapping my code in a system.run() that doesn't work half the time, and giving up on some projects because I'm unable to call some functions in a beforeEvent.
Tested JS Code:
world.beforeEvents.playerLeave.subscribe(({ player }) =>
)
Affects @minecraft/server version 1.3.0-beta and up
Expected Result: Player is teleported to 0, 0, 0 before they leave the realm.
Actual Result: [Scripting][error]-ReferenceError: Native function [Entity::teleport] does not have required privileges. at <anonymous> (main.js:33)
Every function that sets something does not work in a beforeEvent.

Is this only happening on a Dedicated Server, Featured Server, realms, multiplayer or singleplayer? What platform/device are you using?

It's by design for now that in a before event you can't run essentially any "update functions" in a before event, because the rest of the Minecraft infra is in an un-ideal state to be able to process those changes. The main thing is to wrap them in a system.run (which will typically run a half-tick later) in a before event, and you should ensure you "re-fetch" things like entity objects inside of that functions.. Definitely feel that this is somewhat painful..
